Title: Valve seat assembly
Inventor: BOIS LOUIS
IPC: F16K1/42
Filed: 1969-12-18
Abstract: 1,236,879. Valves. LUCEAT. 18 Dec., 1969 [20 Dec., 1968], No. 61653/69. Heading F2V. A seat assembly 10, which is designed to eliminate hammering, comprises a fixed annular and resilient seat 26, and an annular floating seat 42, the two seats being concentric with respect to the axis of flow passage 16 and being disposed on the downstream side of the assembly. The inner seat 42 is movable within an annular recess 36 which communicates with the passage 16 via a plurality of ports 48, and is itself formed with a plurality of axially extending slots 44, such slots co-operating with fixed pins 46 to limit the movement of the seat. In the fully opened condition of a valve incorporating the assembly, the inner seat 42 remains in its lowermost position, i.e. it is contained within the recess 36 (Fig. 1, not shown). Upon the free end 52 of a closure member approaching the assembly, a pressure differential is created across the inner seat 42 as a result of which fluid entering via ports 48 urges the seat into contact with the closure member, as shown. In such condition, a limited flow through the assembly is permitted as long as slots 44 are at least partly outside the recess 36.

Patent GB-750760-A (GB)
Abstract: 750,760. Printing ; feeding sheets &c. KLUSSENDORF, W., KLUSSENDORF, C., and KLUSSENDORF, E., [trading as KLUSSENDORF, H. H., [Firm of]]. June 21, 1954 [July 1, 1953], No. 18158/54. Classes 100 (1) and 100 (2). Stamp-cancelling machines; tripping-arrangements.-In a machine for cancelling stamps on letters which are fed automatically to a continuously-rotating printing-roller 2 and an impression roller 10, the latter being urged resiliently against the roller 2 and automatically tripped therefrom, two feelers 15, 16 are adapted to engage the letters before they arrive at the rollers, these feelers comprising electric contacts arranged in parallel in the circuit of an electromagnet 17 and adapted to close this circuit, if no letter is fed to the rollers, to cause the electromagnet to lift the impression roller 10 away from the roller 2. The printing-roller 2 is in fixed bearings, inked by a roller 21, and driven continuously. The impression roller 10 is carried by one arm 12 of a bell-crank lever pivoted at 11, the other arm 19 being urged clockwise by a spring 13. When the circuit of the electromagnet 17 is closed, the armature 18 thereof engages the arm 19 to lift the roller 10. This circuit is completed when one of the feelers contacts the feed table 14 over which letters 20 are fed, and is only broken when both feelers 15, 16 are bearing on a letter. The feelers are adjustable along a bar 25 so that the tripping and release of the roller 10 can be adjusted, and thus the matter to be printed can be adjusted relatively to the letters. Sheet &c. separators.-The letters &c. are stacked at 22 and separated by a belt 7 engaging a roller 1, driven continuously about a fixed axis, and a roller 5 carried by a two-armed lever 3 pivoted about the axis of the roller 1 and urged counterclockwise by a spring 6. The belt 7 is urged towards a stop member 9 by the spring 6 whereby only one letter at a time can be separated. The stack 22 may be urged upwardly at 23 by spring means, but where letters are to be separated from the stack in overlapping relationship, the stack may be urged upwardly centrally at 24.
Patent GB-762829-A (GB)
Abstract: 762,829. Subaqueous audible and like signalling apparatus. RAYTHEON MANUFACTURING CO. Nov. 10, 1954 [Nov. 23, 1953], No. 32605/54. Class 118 (2). A system of mounting a sound generator for propagating compressional wave energy into a medium through a solid wall by means of a plate of solid material and a pliable material succes. sively located between the generator and the wall and together providing a path through them for said energy which is in effect substantially one half wavelength long, is characterized by adjustable supporting means for tilting said plate and generator together with respect to said wall. A transducer 10, which may comprise a case of hard rubber containing a plurality of crystals or magneto-striction elements mounted therein with electrical connections being made thereto by means of a cable 11, has attached to the bottom thereof a metal plate 12. Bolts 14 extend through bracket members 15 and threadedly engage plate 12. Bracket members 15 are secured to the sides of a box 16 which is rigidly attached to the metal skin 17 of a ship. The interior of box 16 is filled with a fluid, preferably oil, to a level slightly above the plate 12. The spacing between the plate 12 and the skin of the ship 17 is adjusted by rotation of bolts 14 such that the combined thick. ness of the plate 12, skin 17 and oil positioned therebetween is substantially equal to a half wavelength of compressional wave energy through these members at the operating frequency of transducer 10. The bottom cover of the transducer 10 may be made integral with the plate 12. The transducer 10 may be designed so that its inherent impedance is not matched to the characteristic impedance of the water. In this case the thickness of the matching structure comprising plate 12, skin 17, and the oil layer therebetween, would be adjusted such that the impedance of the transducer would be substantially matched to the impedance of the water at the desired operating frequency. Sufficient oil must be used to ensure that the space between plate 12 and the skin 17 is always full of oil even during rolling of the ship or if the unit is mounted on the sloping bottom of a vessel as in Fig. 4. If the bolts 14 are adjusted to make the spacing of plate 12 closer to the skin 17 at one edge the transmitted beam will be deflected from the normal and this may be utilized to produce a vertical beam when the unit is mounted as in Fig. 4. A formula is given for determining the angle of deflection. Compressible rubber or plastic may be substituted for the oil.

IPC: F16D69/02
Filed: 1978-08-08
Abstract: A carbon friction member for use in aircraft brakes is made by forming a reinforcing support of alternating layers of interwoven carbon fibers and layers of individual graphitized elementary fibers oriented to partially penetrate the interwoven fibre layers, impregnating the resultant reinforcing support with a binder and subjecting it to heat treatment to form a blank which is machined, saturated with pyrocarbon and heat treated at graphitization temperatures. The individual graphitized elementary fibers prevent interfiber void formation during firing and also prevent delamination during operation.
Patent GB-2007430-A (GB)
Title: Semiconductor device and fabrication method
IPC: H01L27/10
Filed: 1978-10-11
Abstract: In an MOS device fomed in an epitaxial layer 14 on a highly-doped substrate 12 of the same conductivity type, the thickness of the layer 14 is small compared with the diffusion length of minority carriers in the layer. The diffusion contribution to leakage currents is thereby reduced, and if the difference in dopant concentration between the layer and the substrate is great enough there is also a gettering effect tending to remove minority carrier generation centres from the layer. An application is to dynamic IGFET random-access memories where a reduction in leakage current leads to an increase in hold time. <IMAGE>

Title: Flat-Iron with an Automatic Control System
IPC: G05B11/32
Filed: 1978-11-10
Abstract: In a flat-iron having two heating elements 3 and 4 individually controlled by zero-voltage switches 6 and 7, two temperature sensors 18 and 19 are associated one with each element, and the respective switch 6 or 7 is controlled dependent upon the sensed temperature. A temperature error signal is transferred by each of two gates (12 or 13) from a respective comparator (24 or 25) to the relevant switch (6 or 7), each comparator comparing the voltage drop across the relevant resistance (18 or 19) with a reference voltage. The gates 12 and 13 are enabled only when a signal is received from a common pulse generator 38. An acceleration-sensing switch 40 detects whether or not the iron is moving and inhibits switch-on if it is not. <IMAGE>
